Essays on Radiation

For me radiation therapy is the treatment of cancers with electromagnetic waves, and radiation therapists would be utilizing devices to administer this radiation at the site of cancer in order to destroy cancerous cells.  A radiation therapist would perform the activities concerned with the administration of radiation therapy on the patient, which would be performed…

Abstract The purpose of this report is to present experimental data that demonstrate the relationship between air velocity and surface temperature for a cylinder subjected to forced convection. This experiment will also determine the effects of forced convection on heat transfer from the surface of a cylinder at varying air velocities and surface temperatures. The…

What concept in this chapter are illustrated in this case? What ethical issues are raised by radiation technology?  The concept that illustrated in this case is accountability. Accountability can be define as the responsibility to someone or for some activity. In this case hospital need to find the mechanism to identify the responsible parties for…

There have been many terrible consequences of the Chernobyl accident, the worst of which has been the suffering and death of millions of Ukrainian people due to radiation exposure. One of the most unexplored regions of radiation exposure has been the threat and consequence of cognitive decrements. There has been proven to be many negative factors…

2.1 Introduction In this chapter, a literature reappraisal was carried out so that equal information about the differences in grid and air-gap technique could be gathered with accent on why these techniques are of import in apparent skiagraphy of the sidelong hip. These two techniques will be analysed to explicate better the acquisition of the…

Abstract: A laser is an optical device that emits coherent light (electromagnetic radiation). The term ‘laser’ is an acronym for Light Amplification by Stimulated Emission of Radiation. Typically, lasers are thought of as emitting light in a narrow, low-divergence beam, with a narrow wavelength spectrum (‘monochromatic’ light). Lasers need not have either characteristic, however, it…

Introduction Is food preservation through radioactive materials possible? How can this technology prolong the freshness of foods? Will there be a possibility that the irradiated food products be radioactive? What are advantages and disadvantages of this technology? Food irradiation technology is used to control spoilage and to eliminate disease-causing bacteria in foods. This process can…

Abstract This report investigates the absorbance of methylene blue and carmine red using a spectrophotometer to determine the absorption spectra of both solutions. The concentration of the unknown solution of methylene blue was found to be 1. 07 x 10-5 M by using the molar extinction coefficient, with absorption of 0. 547. It was also…

Not all colourss are the consequence of minus and add-on of visible radiation. Some colourss like the blue sky consequence from the selective sprinkling of the colourss of visible radiation by atoms in the ambiance. The colour scattered by the atoms depends on the size of the atoms themselves. BLUE SKYViolet is scattered more than…

Fiber optics is a branch of optics concerning the transmission of light by means of optical fibers, which are thin strands of glass or other optically transparent materials. Optical fibers can be used to guide light–which is electromagnetic radiation in a certain frequency range–in much the same way that metal wave guides or coaxial cables…
